I have a early 6.0 that will not start cranks and puffs smoke and almost wants to start but it will not start. I hooked the scanner up today and got po113 iat circuit high input ,injectors 1-8 circuit low po261, po275 cyc 5 contribution / balance fault, po341 cam position sensor circuit performance, and p132b turbo charge boost control a perfromance the ficm has 47 volts but as soon as the truck is crancked the ficm voltage just keeps dropping was down to about 32v while cranking . batterys were a little weak but the truck is stuck on a jobsite so i wasnt able to give them a charge . high pressure oil was up to 1500psi plus while cranking so i know the injectors are getting oil . i think that the ficm went and this is a good place to start but i would like to get some other peoples thoughts on this before i go spending money on the wrong parts. any help would be greats thanks
